"I would like to thank Roc Nation Sports, Caribe Promotions and HBO for the opportunity to fight on the biggest Pay-Per-View card of the year. It will be a night of great boxing that fans will not want to miss out on. It’s going to be a chance to show HBO what they want to see. Some say I’m not exciting but it’s not my fault that once my opponents feel my power, they start running and stop throwing punches. Regardless of that, I’m going to give them what they want. I will be standing in the middle of the ring toe-to-toe and putting on a show for the fans. This is where I’ll show the world what my fans got to see in my last fight in the UK against [James] Dickens," said Rigondeaux. "I want to thank Moises Flores for having the courage to step in the ring with me and accepting the mandatory challenge unlike many great fighters in my division. Moises is an exciting Mexican fighter who will bring a fight. I will be ready to exhibit why I am one of the best pound-for-pound boxers and the world’s best at 122 pounds. I’m ready to give fans the best fight out there, and the best is to come the evening of June 17."

I never stopped my preparations from the original date and look forward to making the Mexican fans proud when I defeat the great Rigondeaux."
